Hi - I am unable to upload from a Procomm PC to a ISC2.2 unix host via ymodem. It dies about 20 blocks into the transfer. The set up is as follows: unix host: PD zmodem stuff telebit t1000 ext. modem 9600 baud, running on com2 (standard comm port) 25MHz 386. pc host procomm plus telebit t1000 9600 baud Some people tell me that you cant run 9600 baud. So I step down to 4800, and I still have the problems. They also tell me that ISC2.2's tty buffer is 1K and you cant do 1K block transfer. Now, is that correct? Has anybody done serial transfer at >4800 baud with 1K blocksize using Ymodem or Zmodem successfullly between an ISC2.2 box and a PC? thanks! /bruce

The TTY buffer size is not a problem with proper ZMODEM
implementations on both ends. Unfortunately, some versions of
ISC Unix lock out comm interrupts when writing to disk long
enough to cause errors at 4800 bps and above. Ethernet doesn't
make TTY input any better, BTW.
For further information and hints, please consult the
discussion of "Serial Input Errors" in DSZ.DOC.

Yes - I have sucessfully done 10 zmodem transfers at one time from the ISC 2.2 box - with all the serial lines locked at 19200 baud. Transfers run around 14,000 baud (or 1780 cps on the HST modems). Chances are you are using the ISC ASY supplied driver which is a real dog. I would suggest replacing the driver with the FAS driver and enable hardware flow control. -- Larry Snyder, Northern Star Communications, Notre Dame, IN USA {..!uunet!mailrus!iuvax!ndcheg!nstar!larry, larry%nstar@ndcheg.cheg.nd.edu} backbone usenet newsfeeds available Public Access Unix Site (219) 289-0282 (5 high speed lines)

I use the combination here all the time at 19.2kb with zero problems. >They also tell me that ISC2.2's tty buffer is >1K and you cant do 1K block transfer. Now, is that correct? No, two totally unrelated matters. IF you are using Chuck Fornsberg's rzsz on unix, he uses the standard library fread() and fwrite() calls to pass characters to the comm stream. He does not expect to receive a full block in one fread() and indeed normally gets one. Before we get all spun up trying to help, you need to give us some diagnostic information. What does the status line show before it crashes. And how about running zmodem on the unix system in diagnoistic mode (-v or verbose mode) and tell us what it says or post the tail end of it. Zmodem is normally bulletproof so either you have a bad configuration or bad binaries or something similiar. -- John De Armond, WD4OQC | "Purveyors of speed to the Trade" (tm) Rapid Deployment System, Inc. | Home of the Nidgets (tm) Marietta, Ga | "To be engaged in opposing wrong offers but {emory,uunet}!rsiatl!jgd | a slender guarantee of being right."

This is PROBABLY the reason why. Procomm+'s protocols DON'T WORK! I am suprised that you got 20 blocks. I have tried to use PC+ transfering with several other machines (UNIX and MS-DOS). In most situations, PC+ will allow you to download, but not upload. I don't know why, but PC+ has problems with most of it's protocols, including XMODEM (how does one mess up XMODEM?). My suggestion is to you to use TELIX. It is much like PC+, but WORKS. It is also public domain/shareware. It also comes with ZMODEM (which is faster than YMODEM, IMHO). I have uploaded/downloaded to a directly connected 385/25 UNIX box at 38400baud. The unix box was using rz... Hope that helps. David Kessner kessner!david@csn.org

I have done it here without problems! My suspicion would be Procomm, as it has more bugs than a dog has fleas! Very carefully check the setup in Procomm. If you still have a problem, try using Telix. I'm suggesting this from an experience I had some time ago. Switching to Telix solved the problem...what ever it was as it couldn't be found. Hope this helps! Fred

I don't know why, but PC+ has problems >with most of it's protocols, including XMODEM (how does one mess up XMODEM?). Very untrue. I use both the test drive version of pc+ and a purchased copy. I use it on at clones and ps/2s. I use it with 2400 baud MNP5 modems locked at 4800 baud, V32 full dux modems locked at 19200, and with standard 1200 and 2400 baud modems. Also, direct connected at 19200. Never had a problem using xmodem, ymodem batch, ymodem g or zmodem thru the external interface at any baud rate. I generally get 90-99% rated baud rate thruput talking to Sun and sysv 386 systems running rb/sb, umodem and rz/sz. (Kermit is not a facter, as I like a decent thruput) You have some other problem. It is not Procomm Plus. -- Randy Suess randy@chinet.chi.il.us
